To my knowledge there are only 7 or 8 of the 1991 Convertibles, I bought mine in 2017 from a fellow who owned it since 1994 he said. On power, it is just the standard 305 GM motor and it is a cruiser, not a hot rod at all. I keep kicking around to repower mine, then somedays I think I should sell it and get something else. I do know it gets a lot of attention when we take it out for a ride. They are nice riding and comfortable, just not quick.
